What does zoom mean in camera shooting?

Zooming in camera shooting refers to the function of changing the field of view by adjusting the focal length of the camera lens. By zooming, you can observe from a close distance or a long distance, and you can also zoom in or out of the target object, so that you can observe and record it more clearly. The zoom function of modern camera equipment has become very common, such as surveillance cameras, digital cameras, smart phones and so on. With zoom, camera equipment can better adapt to different scenes and needs, which provides convenience for shooting in our lives.

In the field of monitoring, zooming has become one of the indispensable functions. There are two kinds of lenses for monitoring equipment: long-distance zoom and fixed focus. The former can easily adjust the focal length and viewing angle to better observe the designated area, but due to the attenuation problem in the process of light transmission, the long-distance zoom image is slightly blurred. The latter is very suitable for some scenes that need long-term stable monitoring, such as the capture of evil forces in known areas. No matter what kind of zoom, it can provide more diversified picture display and more comprehensive information recording for surveillance video.

Among photographers, zooming has also received extensive attention. Professional cameras often use high-quality lenses, which can provide more detailed zoom function and support automatic or manual adjustment. Zooming can help us shoot clearer and more vivid pictures at different distances, different perspectives and different environments, and at the same time, we can try some innovations and thinking, such as zooming and panning, to shoot more colorful works.
